USD/CAD LONG TERM SELL

From the daily and weekly time frame I can see that the price is in a downtrend respecting the red descending channel and the red trend line.
Within the red channel in the 4 Hourly time frame the price is in a downtrend following the light blue trend line.

In the Hourly time frame the price broke the purple trend line and retesting back to the trend line (indicating a possible trend line breakout). However, after this breakout of the purple trend line, the price is testing the light blue trend line which was drawn in the 4 Hourly time frame.
Suggesting that the sell is still possible, respecting the light blue trend line.

I expect the price to decrease, as a shooting star candlestick pattern is formed in the blue trend line.
